Abstract
Description
Technical Field
[0001] This utility model relates to the agricultural field, and in particular to a mixing device for soil acidification conditioning liquid fertilizer. Background Technology
[0002] In the agricultural sector, soil acidification is becoming increasingly prominent, seriously affecting crop growth and yield. To improve soil acidification and enhance soil fertility, liquid fertilizers for soil acidification have been widely used. These fertilizers, through the scientific formulation of various raw materials, can precisely neutralize soil acidity, replenish soil nutrients, and create a favorable growing environment for crops.
[0003] The existing method of preparing liquid fertilizers for soil acidification usually involves manually adding the fertilizer raw materials into a measuring container, then placing the measuring container on a weighing device for weighing. If there is too much raw material, some of the raw material needs to be manually removed from the measuring container using tools, and then the weight needs to be measured again. This repeated process of removing and adding materials is cumbersome, labor-intensive, and not convenient to use.
[0004] Therefore, it is necessary to design a convenient mixing device for soil acidification conditioning liquid fertilizer that can easily discharge excess raw materials without requiring manual control of the amount of raw materials. Utility Model Content

[0006] Technical Solution: A mixing device for soil acidification conditioning liquid fertilizer includes a base, a mixing chamber, a discharge nozzle, a level gauge, a water inlet nozzle, a connecting plate, a support column, a weighing device, a weighing bin, a pull-out plate, a mixing head, a stepper motor, and a discharge assembly. The mixing chamber is connected to the upper left side of the base, and a level gauge is connected to the mixing chamber. The discharge nozzle is connected to the lower left side of the mixing chamber, and a water inlet nozzle is connected to the upper left side of the mixing chamber. Support columns are connected to the upper sides of both the front and rear sides of the base, and weighing devices are connected to the upper sides of the support columns. A connecting plate is placed on the upper side of each weighing device, and a weighing bin is connected between the connecting plates. The weighing bin is in contact with the upper side of the mixing chamber. A pull-out plate is slidably connected to the lower part of the weighing bin. A stepper motor is connected between the mixing bin and the base. The stepper motor and the processor are electrically connected through a control module. A mixing head is connected to the output shaft of the stepper motor. A discharge assembly for convenient discharge of excess raw materials is provided on the right side of the weighing bin.
[0007] In addition, it is particularly preferred that both the discharge nozzle and the water inlet nozzle have multiple connection holes.
[0008] In addition, it is particularly preferred that the pull-out panel has a handle on the left side.
[0009] In addition, it is particularly preferred that an ion concentration detector is included, which is connected to the left side of the front part of the stirring chamber.
[0010] Furthermore, it is particularly preferred that the feeding assembly includes a placement platform, a feeding bin, a feeding pipe, a baffle, a servo motor, and an electric push rod. The placement platform is connected to the right side of the base, and the feeding bin is placed on the placement platform. The feeding pipe is connected to the right side of the weighing bin, and the servo motor is connected to the rear right side of the feeding pipe. The weighing devices are all electrically connected to the servo motor. The servo motor and the processor are electrically connected through a control module. The baffle is connected to the output shaft of the servo motor, and the baffle is rotatably connected to the feeding pipe. The electric push rod is connected to the upper right side of the weighing bin. The electric push rod and the processor are electrically connected through a control module, and the telescopic end of the electric push rod is connected to the feeding pipe.
[0011] Furthermore, it is particularly preferred that the discharge pipe is a corrugated pipe.
[0012] Beneficial effects: This utility model starts a servo motor to drive the baffle to rotate and open, allowing some of the raw material in the weighing bin to fall into the discharge bin through the discharge pipe. Then the baffle rotates to close, and the electric push rod is started to drive the discharge pipe to bend upward, causing the raw material in the discharge pipe to fall back into the weighing bin. This achieves the effect of conveniently discharging excess raw material without the need for manual control of the amount of raw material, making it convenient to use. Attached Figure Description

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0020] A device for preparing liquid fertilizer for soil acidification conditioning, such as... Figure 1 , Figure 4 and Figure 5 As shown, the system includes a base 1, a mixing chamber 2, a discharge nozzle 3, a level gauge 4, a water inlet nozzle 5, a connecting plate 6, an ion concentration detector 7, a support column 8, a weighing device 10, a weighing bin 11, a pull-out plate 12, a mixing head 17, a stepper motor 18, and a discharge assembly. The mixing chamber 2 is connected to the upper left side of the base 1. Both the discharge nozzle 3 and the water inlet nozzle 5 have six connection holes for easy connection. A level gauge 4 is connected to the mixing chamber 2. The discharge nozzle 3 is connected to the lower left side of the mixing chamber 2. The water inlet nozzle 5 is connected to the upper left side of the mixing chamber 2. An ion concentration detector 7 is connected to the front left side of the mixing chamber 2. The base 1 has a degree detector 7 and a support column 8 connected to the upper sides of both the front and rear. A weighing device 10 is connected to the upper side of each support column 8. A connecting plate 6 is placed on the upper side of each weighing device 10. A weighing chamber 11 is connected between the connecting plates 6. The weighing chamber 11 is in contact with the upper side of the mixing chamber 2. A pull-out plate 12 is slidably connected to the lower part of the weighing chamber 11. A handle is provided on the left side of the pull-out plate 12 for easy gripping. A stepper motor 18 is connected between the mixing chamber 2 and the base 1. The stepper motor 18 and the processor are electrically connected through a control module. A stirring head 17 is connected to the output shaft of the stepper motor 18. A material discharge component is provided on the right side of the weighing chamber 11.
[0021] like Figures 1-3As shown, the feeding assembly includes a placement platform 9, a feeding bin 13, a feeding pipe 14, a baffle 15, a servo motor 16, and an electric push rod 19. The placement platform 9 is connected to the right side of the base 1, and the feeding bin 13 is placed on the placement platform 9. The feeding pipe 14 is connected to the right side of the weighing bin 11. The feeding pipe 14 is a corrugated pipe for easy deformation. The servo motor 16 is connected to the rear right side of the feeding pipe 14. The weighing devices 10 are all electrically connected to the servo motor 16. The servo motor 16 and the processor are electrically connected through a control module. The baffle 15 is connected to the output shaft of the servo motor 16. The baffle 15 is rotatably connected to the feeding pipe 14. The electric push rod 19 is connected to the upper right side of the weighing bin 11. The electric push rod 19 and the processor are electrically connected through a control module. The telescopic end of the electric push rod 19 is connected to the feeding pipe 14.
[0022] When using this device, first place the base 1 in the liquid fertilizer mixing area, then add the raw materials for fertilizer mixing into the weighing bin 11, allowing the raw materials to fall onto the pull-out plate 12. The materials are then weighed by the weighing device 10 on the support column 8. If too much raw material is added, the processor activates the electric push rod 19 via the control module, causing one end of the discharge pipe 14 to move downwards, resulting in an inclined state. Then, the processor control module activates the servo motor 16, causing the baffle 15 to rotate to a certain angle and open, allowing some of the raw material in the weighing bin 11 to fall into the discharge bin 13 through the discharge pipe 14. When the raw material in the weighing bin 11 reaches the required weight, the servo motor 16 controls the baffle 15 to rotate and close, and then the electric push rod 19 is activated again, causing its telescopic end to retract, moving the discharge pipe 14 towards... The upward bending deformation causes the raw material in the discharge pipe 14 to fall back into the weighing chamber 11, thus facilitating the discharge of excess raw material without the need for manual control of the amount of raw material. This makes it convenient to use and improves the mixing efficiency. Then, the pull plate 12 is moved to the left to open, allowing the raw material to fall into the mixing chamber 2. Water is then connected to external pipes through the discharge nozzle 3 and the water inlet nozzle 5, allowing water to enter the mixing chamber 2 through the water inlet nozzle 5. The water inlet is controlled according to the liquid level detected by the level gauge 4. Then, the stepper motor 18 is started to drive the stirring head 17 to rotate, and the stirring head 17 is used for mixing and mixing. During the mixing process, the ion concentration detector 7 detects the specific ion concentration in the solution. The required amount of raw material can be controlled according to the detected ion concentration. After the mixing is completed, the liquid fertilizer is discharged from the pipe on the discharge nozzle 3.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
